Constitutional Law Confusion: Doctrine of Severability vs Doctrine of Constitutional Avoidance

Maine kaha hain ki maine 3 mahino se laga hua hai kya hai doctrine of severability aur doctrine of constitutional avoidance. Dono mein kya fark hai exactly? Aap logon ko kya lagta hai ki kya yaha dono hi ek hi cheez hai? Maine pehle sochi thi ki yaha dono hi ek hi cheez hai, par ab maine pehchaan li hai ki ismein kuch difference hai. Lekin main thoda confused hoon. Kyaa aaplogon ko pata hai kya difference hai yaha dono concepts ke beech?

Kuch saari examples share karo jisse main samaj sake. Maine kaha hain ki AP LAWCET ki padhai kar rahee hoon.
